DUDLEY S. SEYMOUR, 0F PARK, ILLINOIS, ASSIGNOR T0 UNION SPECIAL MACHINE COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

FILLED-BAG-SEWIN G MIAOHINE.

To all whom it mayconcern Be it known that I, DUDLEY S. SEYMOUR, a citizen of the United States, residing at Oak Park, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Filled-Bag-Sewing and more particularly to machines of this type which are especially adapted to Operate upon small sacks orbags which can be easily fed to the machine by hand.

An object of the invention is to provide a machine of the above character with means for operatin the stitching mechanism which shall be simp e in construction and readily controlled by the operator so as to stop and start the stitching mechanism.

Afurther object of the invention is to provide a device of the above character wherein the motor for operating the stitching mechanism is capable of being shifted.

so as to engagethe operating devices for the stitch forming mechanism, or be disengaged therefrom, and when disengagedfrom said devices, the brake is applied thereto for stopping the stitching mechanism all of which parts are controlled by atreadle accessible to the operator. Y r

A further object of the invention is to provide means whereby the speed of the driving parts of the stitching mechanism may-be varied without changing the speed of the motor. 7

These and other objects'will in part be obvious and will in part be hereinafter more fully described.

In the drawings, which show by way of i illustration one embodiment of the inven- The invention consists, generally, in providing a filled bag sewing machine which Specification of Letters Patent. Patgntgdl 1 1111, 19y 'y Application filed. Ma a, 1.914. Serial No. 836,220. F

consists of a main standard on which is adjustably mounted a table or a rest for the bags which. are being stitched. At the top of this standard there is a bracket which supports a sewing machine which is connected so as to overhang the support on the standard and theneedle reciprocates in substantially a horizontal plane for stitching and closing the mouth of'the bag.

The main driving shaft is provided with an enlarged friction disk. The motor for driving'the stitching mechanism is mounted in a swinging frame on the bracket and carries a friction wheel adapted to be brought intocontact with the friction disk on the main shaft of the sewing machine. The motorframe is swung in one direction by a spring and in the other direction by 'a treadle. This motor supporting frame is also provided with a brake arm which engages the under face of the friction disk on the main shaft of the sewing machine for stopping the same when released from its driving connection.

Referring more 1n detail to the drawings,

my improved filled bag sewing machine consists of a base 1 from which rises a tubular standard 2. At the upper end of the tubular standard there is a bracket 3 which is secured to the standard by suitable bolts 4 which pass through a flange at the lower end of the bracket 3 anda flan e at the upper end of the tubular standar 2. The bracket 3 is formed with a base plate 5 which extends slightly above the top of the bracket. A sewing machine 6, which is preferably 0f the cylindrical bed type is secured to this supporting base plate 5 by suitable bolts 7 The sewing machine as herein shown is provided with a cylindrical bed plate 8 and a depending arm 9. A needle bar 10 reciprocates in said arm and carries a needle 11. The needle bar is reciprocated by a needle lever 12 Which is oscillated by a link 13 which cooperates with an eccentric on the main shaft 14 of the sewing machine. A looper cooperates with the needle and is oscillated by a link 15 from the needle lever extension. These parts are of the usual construction.

On the main shaft 14 of the sewing machine is a friction disk 16. This friction disk is formed with a depending collar 17 which is screwedto the main shaft. The main shaft is also provided with a thrust bearing 18 which carries the end thrust of the shaft. The standard of the machine also carries a bearing roller 19 which is journaled in a bra'bket 20 screwed to said standard. This roller 19 engages the under face of the friction disk 16.

The mechanism of the sewing machine, that is the needle, the looper, and the feeding mechanism thereof, are each operated from the main shaft 14 through a rotation of the friction disk 16. This disk 16 is rotated by an electric motor 21; The outer casing of the motor 21 is formed with projecting lugs 22, see Fig. 2 which are engaged by pivot bolts 23, 23, W ich pivot bolts in turn are mounted in lupwardly projecting arms 24, 24 of a yoke '25. This yoke 25 is adjustably attached to the bracket 3. As

herein shown, the yoke at the bottom face thereof has a transverse rib 26, see Fig. 4,

- which fits in a recess 27 in the upper face of the bracket 3.. The bracket 3 is formed with slots 28, 28, and bolts 29, 29 pass through supported in the yoke 25 so that the friction wheel 31 may be swung toward and from the friction disk 16. A suitable spring 32 is attached at one end to a lug 33 on the motor casing and at the other end to a lug 34 formed integral with the yoke 24. This spring normally swings "the motor so as to raise the friction wheel 31 from contact with the friction disk 16.

An arm 35 is made to conform to the motor casing 21 and is secured thereto by suitable screws 36. This arm projects forwardly underneath the armature shaft 30 to a position substantially opposite the friction wheel 31. On the extreme outer end of the arm there is a brake shoe 37 The brake shoe underlies the friction disk 16 and is adapted to engage the, under face thereof when the motor is swung on its supporting pivots so as to move the friction wheel 31 out of engagement with the disk. This movement of the motor, which brings the brake shoe into contact with the friction disk 16 is caused by the spring 32. The motor 21 is swung in the opposite direction against the tension of the spring 32 by a treadle 38. This treadle 38 is pivoted at 39 at each side of the standard 2 and the treadle arms are connectcdby a treadle board 40. A rod 41 is attached to one of the arms of the treadle at one end, and at its upper end is attached to a lug 42 formed integral with the arm 35, which is mounted on the motor casing. This rod 41 is made in two sections, which are adjustably connected together by suitable collars 43, 43.

A casing 44 surrounds the friction wheel 31, except at the side thereof adjacent the friction disk 16 and this casing is provided with suitable supporting arms which are screwed to the arm 35.

Beneath the sewing head there is a support 45 or rest for the bags to be stitched. This support is carried by a sleeve 46 which surrounds the tubular standard 2 and is adjustable up and down thereon to suit different lengths of bags. The sleeve 46 is held in adjusted position by clamping bolts 47. 47 which pass through the sleeve and may be set up against the outer face of the tubular standard 2. To facilitate the turning of the bolts, each bolt is provided with a handle 48. A cord, or other flexible member 49, is attached to a lug 50 carried by the sleeve 46, and this member passes over a grooved pulley 51 mounted in a bracket 52.

carried by the head of the tubular standard 2. The side of the standard is slotted to permit the placing of the pulley and the passing of the cord or flexible member over the same.

A weight 53 is attached to the lower end of said cord or flexible member and serves to counterbalance the weight of the support or rest 45.

The operation of my device is as follows:

The bags to be stitched are placed on the rest or support 45 and the mouth of the bag directed to the stitching mechanism of the sewing machine. The operator depressing the treadle 38 will swing the motor casing so as to bring the friction wheel 31 into contact with the friction disk 16 and this causes said disk to be operated as the armature shaft rotates. This movement of the motor to bring the friction wheel into contact with the friction disk also moves the brake shoe 37 out of contact with the friction disk and releases the same forfree rotation. The downward pressure of the operator on the treadle tends to force the disk 16 downward The roller or wheel 19 directly underneath the disk forms a support for the disk 16 and takes up this downward thrust. The bearing 18 also serves to relieve the end thrust on the shaft of the sewing machine when the friction wheel is forced into contact with the friction disk.

When the bag is stitched, the operator rehatchet therefore, that the stitching mechanism may be thrown into action at the will of the operator very quickly and may be again stopped While the fabric is being. properly placed relative to the stitching means. When the treadle is released, the spring 32 normally holds the driving connections separated so that the above mechanism operates automatically to stop the machine and the machine is manually thrown into action.

By releasing the bolts 29 the yoke supporting the motor casing may be shifted toward or from the axis of the disk 16 and may be again secured in adjusted position. This shifting of the yoke and the motor moves the friction wheel 13 either toward or from the center of the disk 16, depending upon the direction of movement of the yoke. hen the friction wheel is moved toward the center of the disk, the speed of the sewing machine will be increased and when said friction wheel is moved away from the center of the disk, the speed will be decreased. This permits the varying of the speed of the stitching mechanism for any given speed of the motor. Inasmuch as the spring 32 is connected at one end to the yoke and at the other end to the casing of the motor, this shifting of the parts for varying the speed of the driving mechanism for the sewing machine does not change the tension on the spring.

It will be obvious that minor changes in the details of construction and the arrangement of the parts may be made without departing from the spirit of the invention as set forth in the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
